Description

The Voith Linear Jet combines the best properties of propellers with the best properties of waterjets. Low installation complexity, low sensitivity to marine growth, sustained high efficiency across the vessels' speed range and high bollard pull are borrowed from the propeller side. Reduced vessel draft, the ability to reach high speeds with high efficiency and low noise and vibration levels are borrowed from the waterjet side. The Voith Linear Jet (VLJ) is a fully submerged customshaped deceleration/acceleration nozzle with a stator section aft of the rotor. The stator section cancels rotor-induced swirl, and through that, optimizes the acceleration of the jet stream and the rudder inflow. The submerged position eliminates the requirement for a long inlet tunnel resulting in linear in- and outflow and low marine growth sensitivity. The resulting benefits of this natural flow path without redirections are increased efficiency and reduced noise and vibration levels. For each vessel application a thorough hull integration study is performed and in combination with the special nozzlefastening mechanism, it maximizes nozzle thrust generation and minimizes nozzle drag up to high speeds.
